Decarbing should have no degrade when making carts. I decarb all of my rosin, and I only make vape carts, never edibles. I use only terp liquify to thin it also, If its too thick I use a bit of EJ Mix, but its usually thin enough to push through the carts I use.
I press for 3.5 to 4 minutes also. Sometimes less but never over 4 minutes. And that is total time.
